jsonata is vulnerable to Regular Expression Denial of Service (ReDoS)
75
High Risk
This Affects:
jsonataTL;DR
The JSONata $toMillis function used an inefficient ISO 8601 validation regular expression. Before the fix, applications that evaluated user-provided JSONata expressions could spend excessive CPU processing crafted date strings, causing resource exhaustion and denial of service. Version 2.2.0 tightens the regex structure to avoid inefficient backtracking.
